Google has launched a new feature on Gmail called Quick Actions, which allows users to perform certain relevant actions without having to open e-mail messages. Gmail users can RSVP for events, modify reservations (OpenTable), view shared folders on the cloud (Dropbox), view finished video uploads (Vimeo and YouTube), and write restaurant reviews (Seamless) with just one click.
The Quick Actions buttons will appear to the right of an e-mail’s subject line.
The actions include “Add to Queue” and “View Folder.” The Quick Actions have to be created by the sender though. The person that creates the e-mail needs to specify the action and provide information on how it works.
